Engineering Specification
The projected beam type smoke detector shall be a 4-wire 12/24
VDC device to be used with a separately supplied 4-wire control
panel. The OBSD shall be listed to U.L. 268 and shall consist of an
integrated transmitter and receiver. The detector shall operate
between a range of 16.5 ft. to 330 ft. (5m to 100m). The
temperature range of the beam shall be -4°F to 131°F (-20°C to
+55°C). The beam detector shall feature automatic gain control
which will compensate for gradual signal deterioration from dirt
accumulation on the lenses. The unit shall be capable of mounting
directly to the wall or to a surface back box. Testing shall be carried
out by using a calibrated obscuration test filter. The Reflective beam
type smoke detector shall be a FFE Ltd. 50RU (16.5ft-60ft /
5m-50m) or 100RU (160ft-300ft / 50m-100m).

The Fireray 50/100RU system is a reflective beam smoke detector,
which comprises of a single unit incorporating an infra-red transmitter
and receiver. The signal generated in the transmitter element and
reflected by the prism back to the receiver element is analyzed for the
presence of smoke. The internal microprocessor determines an alarm
condition when a predetermined level is reached.
The product is designed to be mounted so the beam will project
between 19" (0.5 m) and 24" (0.6m) below and parallel to the ceiling.
Lateral detection may be up to 30ft. (9.144m) on either side of the
beam, providing a maximum total coverage area of up to 19,800
square feet (60ft. x 330ft. or 18.29m x 100m). For installations
complying with UL268/NFPA72, the maximum distance of Detector
and Reflector from the ceiling must be 10% of the distance between
floor and ceiling.
